Objective To investigate the relation between the expression of vascular endothelial growth factor (VEGF) and type Ⅳ collagen and the renal lesion of diabetes mellitus in diabetic rats. Methods Wistar rats were divided at random into normal control group(NC group) and diabetic model group(DM group), each group containing 20 animals. The rats models of diabetic mellitus were induced by streptozotocin(STZ). At the 8th week after induction, the expression levels of VEGF and type IV collagen in the kidney tissues in the two groups of rats were detected using immunohistochemistry. At the same time, the renal function of the rats was measured. Results At the 8th week,the expression levels of VEGF and type IV collagen of kidney tissues in DM group was much higher than those in NC group(P

This article was aimed to research the processing methods of Mongolian Meng-Gen-Wu-Su. Ancient and modern literatures which are related to the processing methods of Meng-Gen-Wu-Su were reviewed, summa-rized and sorted . The results showed that the traditional Mongolian Me ng-G e n-W u-Su processing method began in the eighteenth century in the book of Bi Y ong Y ao Ji Zhu Pin . The processing methods of all previous dynas-ties can be classified into three steps, which are descaling, detoxicating and specific drug processing. The pro-cessing methods contain soft, heat, cold, even, obvious, fierce, slow, white, black, speed and hard method. Among these 11 kinds of processing methods from all previous dynasties, some of them use the same processing name but the processing method are different; and some of them use different processing name but the processing methods are the same. Hence, there are 7 kinds of processing methods according to the processing content. Among them, the sulfur processing of Me ng-G e n-W u-Su is widely applied . This processing method is still used today and it can be divided into two kinds, which are the heat process and cold process. This method was originated from the fierce processing and even processing method in the book of Gan Lu Si Bu. And steps of descaling and detoxicat-ing in the processing are ignored. Other processing methods have rarely been used or not used at all. It was con-cluded that the sulfur processing method of Mongolian Me ng-G e n-W u-Su is still used until now .

Seasickness is a leading factor causing reduction in battle efficiency, and psychological factor is one of the important factors influencing the development and progression. This article reviews the mechanism, affecting factors, predictive indications, prevention and treatment of seasickness from a psychological perspective, in an attempt to provide psychological guidelines for military training, enhance the anti-seasickness ability of military staff and decrease its incidence.

The expressions of vascular endothelial growth factor(VEGF)and pigment epithelium derived factor(PEDF)in the tubulointerstitium were determined by immunohistochemistry in the streptozotoein-induced diahetic rats.The mRNA expressions of VEGF and PEDF in normal rat kidney (NRK) were measured by using RT-PCR under different high glucose conditions.The results showed that VEGF expression increased and PEDF expression decreased in the kidney tissue of the streptozotocin-induced diabetic rats.Hiish glucose increased VEGF expression and decreased PEDF expression in N RK cells in a time-and dose-dependent manner.The unbalanced expressions of VEGF and PEDF may play an important role in the occurrence and progression of diabetic nephropathy.
